"By 2018, green MEG production could be more than 30% of
total MEG used in PET [polyethylene terephthalate]," Goyal
said.

By number, that would be almost 3,000 KT of green MEG
production -- up from about 400 in the current year of 2014.

Goyal explained that his company's integrated ethanol to EO/EG process offers
several competitive advantages, including the flexibility to
design for excess bio-ethylene production with a quality
suitable for other downstream products such as vinyl chloride
monomer (VCM) and high-density polyethlyne (HDPE).

Scientific Design, which has 25 years of operating experience
with bio-EO/EG, notes that its process producers fiber-grade
MEG quality -- the same as with petro-ethylene. Moreover, the
company says it has strong research and development (R&)
support for continuous improvements in process efficiency and
the handling of ethanol from traditional and
second-generation raw materials.

"This process addresses a niche but growing market for green
glycol," he said. "It's a viable option fo rregions where
petro-ethylene is either too expensive or not accessible. It
also provides flexibility to switch between petro- and
bio-ethylene based on factors such as current raw material
costs and market demands."

The Scientific Design technology can also be a major
process link for other ethylene- or EO/EG-based bio-products,
Goyal explained.
